Shown here are scenes of destruction from the major earthquake, magnitude 6.6 on the Richter Scale, that struck the Los Angeles, California, area at 6:00:41.5 A.M. PST (9:00:41.5 A.M. EST) Tuesday. February 9, 1971. The quake resulted in sufficient damage to warrant a ‘major disaster’ declaration by President Nixon. Heavy damage was reported in central and northern Los Angeles, particularly the San Fernando Valley and the suburban towns of Newhall and Saugus. Collapsed freeway overpasses, fissures in roadways, and numerous fires caused by ruptured gas mains resulted from the earthquake. Some minor cracks in the faces of two reservoir dams in the San Fernando Valley caused some water leaks, with the subsequent evacuation of nearby valley residents.
